Aluminum-, magnesium- and calcium-organic polymer-based batteries (AMPERE)

该项目的目标是为铝、钙和镁基电池系统设计优异的聚合物电极材料和电解质，利用有机氧化还原聚合物作为阴极活性材料的有利特性，提供高体积和重量能量密度和安全性，同时在生产过程中环境足迹小。我们将开发更环保的有机氧化还原聚合物作为正极材料的合成路线，不需要化学量的过渡金属，我们将研究镁基和钙基电池中的高容量n型氧化还原聚合物以及铝基，镁基和钙基电池中的p型氧化还原聚合物。除其他目标外，将为铝基和钙基电池开发无氟电解质，并为不需要过量金属的镁基和钙基电池探索“无阳极”概念。机械实验研究将使我们了解离子在聚合物基电极中的插入过程。

The goal of the proposed project is to devise excellent polymer electrode materials and electrolytes for Al-, Ca- and Mg based battery systems that utilize the favorable properties of organic redox polymers as cathode-active materials and offer high volumetric and gravimetric energy densities and safety, combined with a small environmental footprint in production. We will develop environmentally more sustainable synthetic routes to organic redox polymers as positive electrode materials, which do not require stoichiometric amounts of transition metals, we will investigate high-capacity n-type redox polymers in Mg- and Ca-based batteries as well as p-type redox polymers in Al-, Mg- and Ca-based batteries. Fluorine-free electrolytes will be developed for Al- and Ca-based cells, and “anode-free” concepts explored for Mg- and Ca batteries, which do not require excess amounts of metal, among other objectives. Mechanistic experimental investigations will allow to gain understanding on the ion insertion processes in the polymer-based electrodes.
